WeChat applet payment countdown function in Android

Look at the effect

#Due to my weak web experience - - At first, my idea was to find events, but after looking at the API for a long time, it was basically click and touch, triggered by physics. - -

I actually ignored the life cycle. Life cycle + threads are completely OK~

It turns out that threads are still king. This should be done from the beginning~

I also read a lot of things written in js on Du Niang, but maybe I have just done it a few days ago, and I am not proficient enough in js and WeChat applet

Thoughts:

: Function (Options) Currency Method Method

## Defining threads for data dynamic reality

##1. Date converts to milliseclic seconds

# #2. Definition thread dynamic display

3. Rendering the rendext

## 1. milliseconds to turn into a fixed format

# 2. If there are insufficient digits, add 0

Look at the code

wxml:

<view class="pay_time">
 <image src="{{imgUrls_pay_time}}"></image>
 <text>支付剩余时间：</text>
 <text>{{clock}} </text>
</view>

wxjs:

// pages/order/take_order/pay/pay.js
var app = getApp()
Page({
 data: {
  imgUrls_pay_time: '/image/icon_orderstatus_countdown.png',
  "productName": "",
  "productPrice": "",
  "payDetail": [],
  "wxPayMoneyDesc": "",
  "expireTime": "",
  clock: ''
 },
 onLoad: function (options) {
  // 页面初始化 options为页面跳转所带来的参数
  new app.WeToast()
  var that = this;
  that.count_down();
 },
 onReady: function () {
  // 页面渲染完成
 },
 onShow: function () {
  // 页面显示
 },
 onHide: function () {
  // 页面隐藏
 },
 onUnload: function () {
  // 页面关闭
 },
 /* 毫秒级倒计时 */
 count_down: function () {
  var that = this
  //2016-12-27 12:47:08 转换日期格式
  var a = that.data.expireTime.split(/[^0-9]/);
  //截止日期：日期转毫秒
  var expireMs = new Date(a[0], a[1] - 1, a[2], a[3], a[4], a[5]);
  //倒计时毫秒
  var duringMs = expireMs.getTime() - (new Date()).getTime();
  // 渲染倒计时时钟
  that.setData({
   clock: that.date_format(duringMs)
  });
  if (duringMs <= 0) {
   that.setData({
    clock: "支付已截止，请重新下单"
   });
   // timeout则跳出递归
   return;
  }
  setTimeout(function () {
   // 放在最后--
   duringMs -= 10;
   that.count_down();
  }
   , 10)
 },
  /* 格式化倒计时 */
 date_format: function (micro_second) {
  var that = this
  // 秒数
  var second = Math.floor(micro_second / 1000);
  // 小时位
  var hr = Math.floor(second / 3600);
  // 分钟位
  var min = that.fill_zero_prefix(Math.floor((second - hr * 3600) / 60));
  // 秒位
  var sec = fill_zero_prefix(second % 60);// equal to => var sec = second % 60;
  return hr + ":" + min + ":" + sec + " ";
 },
 /* 分秒位数补0 */
 fill_zero_prefix: function (num) {
  return num < 10 ? "0" + num : num
 }
})

tip:

If the digits are not padded with 0

, the following will be displayed
